Space 3 Dage Div. will maintain its own space (last year it shared with Gates Radio Co.), displaying mobile studio console, Tele-Tran BackrPack, fully-transitorized twin sync generator and other equipment. Tele-Tran unit is designed for political conventions and other remote purposes and weighs 13-14 pounds with battery. New ETS mobile studio console accom modates three-camera system and is flexible for remote use and for expanding transmitter operations at reasonable cost. Dage has fixed and mobile consoles for complete broadcast service and compatible for closed circuit tv operation. Personnel: J. L. Leahy, Dale Schonmeyer, Allan Finstead, Joe Alinsky, Wells Chapin, Lloyd Matter, Bill Elmander. ELECTRONIC APPLICATIONS INC. Space 6 Included in the display will be EMT 940 turntable, EMT special cables and other units, portable tape recorder, studio and field microphones and fm operations relay receivers. Personnel: John Costello, Trims M. Skee, Vincent J. Skee. FAIRCHILD CAMERA & EQUIPMENT CORP. Space 9 A The "Mini-Rapid" F316A automatic film processor will be demonstrated by Fairchild. This is an automatic, leaderless. loading and self-threading unit. Fairchild will show its "Cinephonic-16" magnetic sound camera — a hand-held, single system 16mm camera. Personnel: Herbert M. Oshan, Gerard J. Morio, Homer B. Voorhest, Richard Goldberg. FOTO-VIDEO LABS INC. Space 19 The new V-515 Vidicon camera and control unit will highlight the Foto-Video Labs' display of new equipment. The instrument, small enough without its lens system to store in an overcoat pocket, is modularized and has power controls that safeguard the circuit from shorts and overloads. Other equipment on display will be highdefinition live tv cameras, utility and professional monitors, transistorized power supplies, closed-circuit sync generator (portable and rack mounted), video test centers and foto products. Personnel: A. J. Baracket, T. R. Kennedy Jr., S. Joseph Carris, Don Foyer, Joe Kaspar, Hans Nord, Larry Nagy, R. D. Hamilton. GATES RADIO CO. Space 2 New equipment to be exhibited by Gates will include the FM-10A 10 kw fm transmitter, professional 12-inch transcription turntables and an M-5693 modulation monitor. Gates' fm transmitter features a new development called varialine tuning, a method of tuning a single ended vhf amplifier. A portion of a parallel plate transmission line is made variable to capacity tune the line to operating frequency, with neither mica nor vacuum capacitors needed in the tank turntable. The 12-inch turntable is identical to older models except for its more compact size. Other Gates products to be on display: 5 kw am transmitter, with silicon rectifiers; 5 kw tv transmitter for both color and black and white; 1 kw am transmitter; two spot tape recorders (accommodating 101 spot announcements on separate tracks and using an indexing system for selection). The tape itself is a vertical-playing belt 13 inches wide. In addition there are several speech input systems, remote amplifiers, frequency monitors, leveling amplifiers and the Nite Watch automatic programming system. Personnel: P.S. Gates, Larry Cervone, Norbert Jochem, Edward Wilder, John Price, Gene Edwards, Franz Cherny, Tom Humphrey, CO. Morgan, Bill Moats, Dick Spruill, Joe Engle, Bob Hallenbeck, London England, Urlin Whitman, Wally Warren, Abe Jacobowitz, Stan Whitman. GENERAL ELECTRIC CO. Space 31 A new tv film projection claimed to inject new life into old films will be shown by General Electric. It was designed by Eastman Kodak Co. for GE, to be used with the Vidicon camera. Eastman's new 16 mm continuous tv projector (Model 350) "is the most significant development in tv projection in 15 years," according to John Wall, GE broadcast sales manager. "Now local stations can combine the economy of 16 mm projection with 35 mm quality." Effects of scratches and dirt particles are practically eliminated and a steadier image is produced on the screen, he said. The improved image is attained through an optical system using tilting, rotating mirrors that follow the film as it passes over the projection gate, reflecting an immobilized and stable image into the system, it was explained, with additional steadiness attained by the projector's capacity to compensate automatically for film shrinkage. Full capabilities of the GE Vidicon camera are utilized by applying an image to the tv system 100% of the time as opposed to the 30% to 50% light application found in conventional intermittent projectors, according to GE. The film moves over the projection gate without clamping, extending print life. Film motion can be reversed for cueing or stopped for still projection at any time. The system can be adapted to all tv systems. Other products in the exhibit will include a new tv studio monitor (TM-21-A) and other monitoring equipment; several lines of cameras; a 10 kw low and highchannel vhf transmitter (TT-32-B), other audio and video equipment and microwave units. A hospitality suite (Room 1500) will be maintained. Personnel: Robert L. Casselberry, John Wall, Charles J. Simon, Harold Towlson, Richard Putman, John Jones, Frank Bias, William G. Broughton, Lewis F. Page, Earl H. Piatt, James M. Comer Jr., Thomas F. Bost Jr., Vernon H. Russell, Robert E. Lauterbach, James Douglas, Robert Cochran, Hugh Granberry, Hal Condo, John Watter, C.H. Jensen, A.F. Carl, M.R. Duncan, Charles H. Lake. GENERAL ELECTRONICS LABS Space 35 Products to be shown by General Electronic include 15 kw and 1 kw fm transmitters with fm multiplex exciters. These include main channel exciter, subchannel generator and power supply in integrated cabinet. 92 (NAB CONVENTION PREVIEW) BROADCASTING, March 28, 1960
